Product Descriptions

NY8TM52D is an 8-bit microcontroller with MTP as the program memory, suitable for IO product applications such as remote control, fan/light control, or amusement device peripherals. MTP, as a programming memory tool, is a more convenient and efficient development product. The NY8TM52D core is built on the RISC reduced instruction set architecture, making it easy to edit and control, with a total of 55 instructions. Except for a few instructions that require 2 timing sequences, most instructions can be completed in 1 timing sequence, allowing users to easily control different applications through programming. Therefore, it is very suitable for various complex applications with low to medium memory capacity.

In terms of I/O resources, NY8TM52D has 6 flexible bidirectional I/O pins, each with a separate register to control as an input or output pin. And each I/O pin has additional program control functions such as pull-up or pull-down resistors or open drain outputs. In addition, for infrared remote control products, NY8TM52D has a built-in infrared carrier emission port with selectable frequencies. Among them, 4 I/Os have touch switch function and can be controlled as touch switch input pins through registers. NY8TM52D has a built-in voltage comparator, which can also select I/O as the voltage input and output the comparison result through a register.

The NY8TM52D has two sets of timers, which can be used as general timing applications with system frequency or triggered by external signals to count. In addition, NY8TM52D provides three sets of 10 bit resolution PWM outputs and one set of buzzer outputs, which can be used to drive motors LED、 Or buzzers, etc.
